>Catholics would never post a title like you suggested.
I would not be shocked or offended if a Catholic wrote an article titled Pope Benedict XVI is an Apostle of Jesus Christ.
It is my understanding that Catholics consider the Pope to be the successor to the Apostle Peter. Whether I agree with that premise or not doesn’t matter. My opinion shouldn’t keep them from posting such an article in their caucus.
In fact, I might find the article interesting and informative. But either way, that title certainly wouldn’t offend me.
Would it offend you?
Now they might post a thread titled “The Pope is the Vicar of Christ.” Much more likely than what your postulated.
I give a lot more leeway to Catholicism than Mormonism, as Catholicism is based on the Historical Biblical Jesus while the Mormon belief system has a Jesus that does not fit Biblical criteria.
